Is the advertising screen with changed words the same as the fixed power consumption?

First of all, it should be clear that the energy consumption of luminous signs is not completely fixed, that is to say, not every luminous sign is the same. For example, some signboards are bigger and use more LED lights. In other words, some kinds of light sources are different, and the density of light sources is also different, so the power consumption of LED luminous signs is also different. Even some merchants' luminous signboards are only open for two or three hours every day, while others are always open, so the power consumption is obviously different.

2. The power consumption of general luminous characters can be calculated as follows.

If you want to know the power consumption of luminous signs, you can calculate it like this. According to a square luminous word, there are 400 light bulbs, so ten hours a day, usually almost twice a day, even if it accumulates for a month, it will cost tens of dollars, so it is not very expensive. what do you think?
